|discussion=<p>Although included here, <i>Potentilla erecta</i> is questionably extant as a naturalized species in North America and is not currently known from Newfoundland where historically reported. It is a medicinal plant called tormentil, high in tannins and strongly astringent. A tea made from the tuberous rootstock is widely used in Europe and parts of Asia for diarrhea, dysentery, sore throats, and related problems. A decoction is a mild antibiotic used for cuts and minor infections, especially as an anti-inflammatory for gingivitis and other gum problems. The rootstock is used as a red dye.</p><!--
--><p>Another synonym with a long history of use is <i>Potentilla</i> tormentilla Necker, illegitimate by virtue of being superfluous.</p>
